A54SX08A-2TQ144I

Overview

The A54SX08A-2TQ144I is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 12,000 system gates and 768 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and operates with supply voltages ranging from 2.25 V to 2.75 V. It features a maximum system performance frequency of 250 MHz and an internal clock speed of 350 MHz. The industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for permanent, nonvolatile configuration without external memory requirements.
• Features a sea-of-modules architecture with DirectConnect and FastConnect routing resources to minimize signal propagation delays.
• Supports hot-swap capabilities and mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V PCI, TTL, and LVTTL.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing (JTAG) for enhanced diagnostic and verification capabilities.

Applications

• High-performance digital logic integration requiring deterministic timing and low power consumption.
• Systems requiring hot-swappable components or cold-sparing configurations.
• Industrial control applications operating within extended temperature ranges.
• PCI-compliant interface designs utilizing mixed-voltage signaling.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the '2' speed grade indicates approximately 25% faster performance than the standard grade. Ensure the TQ144 package type matches the design footprint requirements. Check current availability status as legacy antifuse devices may have limited production runs.

Selection Notes

Select this device when 12,000 system gates are sufficient for the design complexity. The -2 speed grade is appropriate for designs requiring up to 250 MHz system performance. Verify that the 113 available I/O pins meet the interface count. Consider the antifuse nature of the device, which prevents reprogramming once configured.

Part Context

This component belongs to the Actel SX-A family of FPGAs, originally developed by Actel Corporation and later acquired by Microsemi, now part of Microchip Technology. The SX-A series is characterized by its high-speed antifuse technology and robust security features, distinguishing it from volatile SRAM-based FPGAs.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Designers migrating from other families should evaluate pin compatibility and logic resource equivalence carefully.

FAQ

What is the programming technology used in the A54SX08A?

The A54SX08A uses metal-to-metal programmable antifuse technology, which creates permanent low-impedance connections upon programming.

Can the A54SX08A be reprogrammed after fabrication?

No, the antifuse technology is nonvolatile and one-time programmable; once an antifuse is blown, the connection cannot be undone.

What does the 'I' suffix indicate in the part number A54SX08A-2TQ144I?

The 'I' suffix denotes the Industrial temperature grade, supporting operation from -40°C to +85°C.
